Travel and Terrain Advice
This is a very dangerous avalanche condition. Even if you are in a below treeline, you need to be vigilant enough for outbreaks and runways in the forest. If an avalanche occurs in a place where there are trees, even if the scale is small, the tree becomes a hazard, and it has a serious ending. Also, since there is a high possibility that an extremely large avalanche will occur, it is necessary to think that a large-scale avalanche will flow from the far upper part even if you are near the foot of the river terrain. Even if you are an experienced person, you need to maximize your safety margin using the terrain. If you skate inside the ski resort, please observe the skidable area. It's not only for your safety, but also for the safety of other visitors. If you enjoy fresh snow on the slopes, I think it's a good day to relax in the hot springs.
